The present invention relates to a tandem organic light-emitting element, more particularly to a tandem organic light-emitting element which may decrease a driving voltage in a driving region of a charge generation layer by sequentially laminating an electronics layer, which is doped with a metal dopant, and an electronics layer, which is doped with an organic dopant, on one side of the charge generation layer, thereby having increased power efficiency and life span. To this end, the present invention provides a tandem organic light-emitting element which is characterized by comprising: a base substrate; a first electrode formed on the base substrate; a second electrode formed opposite to the first electrode; two or more organic light-emitting layers, formed between the first electrode and the second electrode, comprising a light-emitting layer, a hole transfer layer formed between the light-emitting layer and the first electrode, and an electronics layer formed between the light-emitting layer and the second electrode; and a charge generation layer formed between the neighboring organic light-emitting layers, wherein the electronics layer formed between the light-emitting layer and the charge generation layer has a multilayer structure, while comprising a first electronics layer doped with a metal dopant and a second electronics layer doped with an organic dopant.
